For people who got infected with covid then and now

Was it more intense when it first started or now?
For me, I'm getting infected by it every summer. I have it rn, yesterday n today I went cycling, and it was really tiring.
I'm the type who can't leave home without morning yoga, but during these days i had feelings that if i do it i might pass out.
I'm breathing with effort, it's like there's no oxygen in my lungs.
Moreover, i feel a sense of laziness that i can't explain. It's like I've never moved out of bed or know what's sport. It's just really weird how it got me this time.

Almost forgot , does anyone else feel depressed when they get it? I do
